Abstract

In an optical scanning apparatus for scanning incident light two-dimensionally by oscillatory rotation of a reflective surface on which light is incident, an increase in scan rate of light and downsizing of the optical scanner are achieved. To this end, an optical scanner 100 is made to include first and second scanning devices 120, 122. The first scanning device, which has a first mirror portion 150 on which a first reflective surface 140 is formed, is configured to horizontally scan light obliquely impinging on the first reflective surface, by angular oscillation of the first mirror portion about a first oscillation axis. The second scanning device, which has a second mirror portion 180 on which a second reflective surface 142 is formed so as to be generally in parallel to the first reflective surface in a non-active state of the optical scanner, is configured to vertically scan light exiting the first reflective surface and then obliquely impinging on the second reflective surface, by angular oscillation of the second mirror portion about a second oscillation axis intersecting with respect to the first oscillation axis.
